STMicroelectronics has unveiled the STM32V8, a new generation of high-performance microcontrollers (MCUs) for demanding industrial applications. The STM32V8 MCU is designed with ST’s most advanced 18nm process technology with best-in-class embedded phase-change memory (PCM).
It is manufactured in ST’s 300mm fab in Crolles, France, and also in collaboration with Samsung Foundry. MCUs are foundational chips, with the broad portfolio of STM32 devices powering billions of devices on the planet across consumer devices, home appliances, industrial applications, medical devices and communication nodes.
The STM32V8 MCU is the most powerful STM32 MCU ever shipped, with clock speeds of up to 800 MHz thanks to its Arm Cortex-M85 core and the 18nm process technology. A wide variety of safe and connected applications are made possible by high levels of quicker and larger embedded memory.
In challenging operating conditions, the FD-SOI process technology with incorporated PCM offers great robustness and reliability.
One such demanding environment is the high-radiation conditions encountered in Low Earth Orbit (LEO). SpaceX has selected the STM32V8 for its Starlink constellation, using it in a mini laser system that connects the satellites traveling at extremely high speeds in LEO.
